Fixing turbines in storms

摘要

Each turbine in an offshore wind farm requires an average of four visits a year for routine maintenance, as well as unexpected downtime to replace components. Although this may not sound like much, if you consider a wind farm with upwards of 500 turbines, maintenance engineers will be busy all year round. During downtime, the turbines are in an idle state, in which the blades are turned out of the wind and the brakes are applied - essentially, they just sit and wait to be fixed, which costs money.
